Reliability of iCare ic100 Rebound Tonometry and Agreement With Goldmann Applanation Tonometry in Healthy and Post-myopic LASIK Patients.

PRECIS: Rebound tonometry offers excellent reliability for obtaining intraocular pressure (IOP) measurements in healthy and post-myopic laser-assisted in situ keratomileusis (LASIK) patients regardless of corneal parameters and axial length and regardless of the instillation of ocular topical anesthesia. PURPOSE: The purpose of this study was to assess the reliability of rebound tonometry, its agreement with Goldmann applanation tonometry (GAT) and its concordance after topical anesthesia in a group of nonoperated healthy patients and a group of post-myopic LASIK patients. PATIENTS AND METHODS: Fifty-four patients were included in this prospective observational, case-control study. Patients were divided into 2 groups: control (n=32, 26.7±6.1 y) and LASIK (n=22, 35.8±7.6 y). Measurements of IOP were carried out using the iCare ic100 tonometer and GAT. The repeatability, intersession and interobserver reproducibility, GAT interchangeability and concordance after topical anesthesia of the iCare ic100 tonometer were assessed. RESULTS: Clinical reliability of the iCare ic100 was excellent in terms of repeatability [intraclass correlation coefficient (ICC)=0.909 and 0.951 in control and ICC=0.938 and 0.961 in LASIK] as well as interobserver reproducibility (ICC=0.896 in control and 0.916 in LASIK) and concordance after anesthesia (ICC=0.910 in control and 0.972 in LASIK) in both groups. Intersession reproducibility was clinically good in nonoperated patients (ICC=0.758 and 0.849) and excellent in LASIK patients (ICC=0.878 and 0.904), although statistically significant differences were obtained in the control group for both examiners (P=0.003 for examiner 1 and P=0.04 for examiner 2). Agreement with GAT was good in both groups (ICC=0.805 in control and 0.790 in LASIK), although statistically different (P<0.001 and P=0.02, respectively). Finally, the iCare ic100 reliability was independent of corneal parameters and axial length in both groups (P>0.05 for all parameters). CONCLUSIONS: Rebound tonometry offers good or excellent clinical reliability in both healthy and post-myopic LASIK patients. This article highlights the efficacy of iCare ic100 rebound tonometry as a reliable tool for the measurement of IOP and the management of glaucoma in healthy patients and patients undergoing myopic LASIK surgery.

A Novel Surgical Technique for Ahmed Valves in Refractory Glaucoma With Silicone Oil Endotamponade.

PURPOSE: The purpose of the study is to describe a novel technique to implant Ahmed valves in patients with refractory glaucoma because of silicone oil (SO) endotamponade PATIENTS:: Three patients with glaucoma without SO removal were used as an example for this technique. METHODS: Technique report. RESULTS AND CONCLUSIONS: We introduce a standard technique modification for Ahmed valves in patients with SO. This modification consists on locating the Ahmed valve more tangential to the limbus curvature instead of the usual perpendicular position and inserting the tube in the posterior chamber. The tube can be longer and run parallel to pupil. This technique allows use superotemporal quadrant (fewer complications), avoid corneal touch and decrease SO loss through the tube to subconjunctival space.

El glaucoma maligno / Malignant glaucoma

El glaucoma maligno es una forma rara de glaucoma, que suele seguir a la cirugía en pacientes con ángulo cerrado y glaucoma primario de ángulo cerrado. En esta revisión bibliográfica se discuten las características clínicas, la clasificación, la patogenia y el manejo de esta afección. La revisión bibliográfica la efectuamos a partir de una búsqueda en Medline (los principales artículos de PubMed y en Internet) y bases Cochrane (The Cochrane Library). Las imágenes aportadas son propias y las hemos efectuado con tomografía de coherencia óptica SS-1000 de segmento anterior CASIA de Tomey ®. El objetivo de la revisión es revisar las evidencias sobre una afección rara y actualizar los protocolos diagnósticos y terapéuticos con las nuevas técnicas a nuestro alcance. Consideramos que el nombre de glaucoma maligno para esta patología debería evitarse, ya que actualmente con los medios disponibles el pronóstico es relativamente bueno. Es por esto, que preferimos nombres como el síndrome de misdirección del humor acuoso, o glaucoma por bloqueo ciliar(AU)

Malignant glaucoma is a rare form of glaucoma that typically follows surgery in patients with primary angle closure and primary angle-closure glaucoma. In this bibliographic review we discuss the clinical characteristics, classification, pathogenesis, and management. The literature review is based on a search in Medline (the main articles of PubMed, Internet) and Cochrane databases (The Cochrane Library). The images provided we have done them with SS-1000 Optical Coherence Tomography CASIA of Tomey ®. The aim of the review is to review the evidence for a rare condition and update the diagnostic and therapeutic protocols with the new techniques. In addition, the review authors thought that the name of malignant glaucoma for this pathology should be avoided, because of prognosis is relatively good. This is the reason, we prefer names such as misdirected aqueous humor syndrome, or ciliary blockage glaucoma(AU)
